Description

Energy storage apparatus using spring torsion Background of the Invention 1, Field of the invention The invention generally relates to an energy storage apparatus. More particularly, the invention relates to energy storage apparatus that may receive energy from various types of energy sources, store it through spring torsion and output it. 2. Description of the prior art Because there is only a limited amount of petroleum available in the earth, it will definitely be used up some day in the future. In addition, the control and distribution of petroleum resource has been in the hands of few countries. Moreover, the combustion or use of petroleum generates serious impacts on the environment. The development of new energy sources have been an important topic.
In fact, there have been many types of green energy sources, such as solar energy, wind power, hydropower, etc., and will remain available for a long time. However, these types of green energy sources have to be converted into a form that may be used. In addition, they are not stable. For examples, solar energy is not available in nights; wind sometimes is strong and sometimes is weak and thus is not stable; hydropower may becomes unusable during dry seasons. Therefore, a crucial point in the use of a green energy source would be: energy should be stored away when it is supplied plentifully and energy may be output from a device when the output of an energy source dwindles.
Regarding the conversion of energy into a form that may be used, a device that may be used to accomplish such conversion is the invention with the ROC patent number 197,189 (invented by the inventor of the present invention) with the title of “energy storing set in which energy is stored through spring torsion”. Such energy storing set comprises a casing, energy storing units and a transmission box. The energy storing units and a transmission box are housed in the casing. Each of the energy storing units comprises a longitudinal rod, a plurality of rotational disc portions and a plurality of spiral springs. An outer retaining protrusion and an inner retaining groove are provided on each disc portion. A spiral spring is provided between two disc portions and the two ends of the spring are retained by the outer retaining protrusion and inner retaining groove. An energy input axle is provided outside the casing and may pass the energy to drive the first rotational disc portion. In addition, the transmission box has an energy input end and an energy output end. The energy output axle sticks out of the casing. Several cog-wheels are provided inside the transmission box and may engage with a rotational disc disposed inside the box. Therefore, in the energy storing set, energy is stored through spring torsion and then may be output steadily.
Such energy storing set may be used to store energy and output energy steadily. However, such energy storing set has disadvantages. Its biggest drawback is the insufficiency of spring torsion because the conventional spiral springs are used in the energy storing set. Therefore, the efficiency of energy storage is quite low. Another drawback is the single-directional input bearings because there bearings may be damaged easily if the magnitude of torsion that is input into the energy storing set gets too great. Therefore, such energy storing set may be used for small-size energy sources and can not be used for large-size energy sources, such as a power plant.
To eliminate these disadvantages, the inventor of the present invention has put a lot of effort into the subject and has successfully come up with the energy storage apparatus of the present invention.
Summary of the invention The main object of the present invention is to provide an energy storage apparatus that may be used for various types of energy generating unit to store energy through spring torsion and may release energy when the energy generating unit stops to supply energy.
A second object of the present invention is to provide an energy storage apparatus that may maintain a steady energy output.
A third object of the present invention is to provide an energy storage apparatus that has a high efficiency of energy storage and takes up a limited amount of space.
To reach the objects, the energy storage apparatus of the present invention is disclosed. In the energy storage apparatus of the present invention comprises, energy from an energy generating unit is stored in the form of spring torsion and then is output in a steady manner. The energy storage apparatus of the present invention comprises a plurality of cog-wheels, a plurality of torsion magnitude limiting units, a plurality of single-directional input bearings, a plurality of energy storing units and a plurality of speed increasing cog-wheels. A rotational energy source is connected with the cog-wheels and the torsion magnitude and direction of input energy are limited by the torsion magnitude limiting units and single-directional input bearings, respectively. Then, the input energy is stored in the energy storing units through the compression of the springs. The energy in the form of the compression may be output through the speed increasing cog-wheels. If the torsion magnitude exceeds a pre-detennined value of the torsion magnitude limiting units, the torsion magnitude limiting units would interrupt the input of the torsion by the way of idling to prevent the damage of the energy storing units. The single-directional input bearings only allow the single-directional passage of the torsion from each of the twisting force limiting units to the energy storing units to prevent passage of the torsion in the opposite direction so as to protect the torsion magnitude limiting units and cog-wheels. Each of the energy storing units includes at least two end rotational disc portions, which are connected with each other co-axially. A leaf spring unit is provided between each pair of rotational disc portions and one end of the leaf spring unit is bent in an opposite direction (opposite to the winding direction of the leaf spring) and is retained a retaining groove to increase its torsion. The speed increasing cog-wheels are connected with the output end rotational disc portions to increase the rotational speed so as to output the energy. In addition, the energy storing units may be connected in series or in parallel to increase the efficiencies in energy storage and energy output.

List of reference numerals Detailed description of the preferred embodiment Please see Figs. 1 to 3, which illustrate the energy storage apparatus 1 of the present invention. The energy storage apparatus 1 of the present invention comprises a plurality of torsion-converting gear 11 , a plurality of Torsion limiter 12, a plurality of one-way input bearings 13, a plurality of energy storage set Hand a plurality of speed enhancing cog-wheels 15. An energy source is connected with the Torsion-converting gear 11 and the torsion magnitude and direction of input energy are limited by the Torsion limiter 12 and one-way input bearings 13, respectively. Then, the input energy is stored in the energy storage set Hthrough spring torsion. The stored energy may be output through the accelerating gear 15.
In detail, first, when the energy is input, the torsion prompts the Torsion-converting gear 11 to rotate. Then, if the magnitude of the torsion exceeds a pre-determined value of the Torsion limiter 12, the Torsion limiter 12 would interrupt the input of the torsion through idling to prevent the damage of the energy storage set 14. Each of one-way input bearings 13 is connected with the output end of the corresponding torsion magnitude limiting device 12 and only allows the single-directional passage of the torsion from each of the Torsion limiter 12 to the corresponding energy storage set 14, preventing passage of the torsion in the opposite direction so as to protect the Torsion limiter 12 and Torsion-converting gear 11. Each of the energy storage set Hincludes at least two end rotational disc 142 and 143, which are connected with each other co-axially. A torsional spring 141 is provided between each pair of end rotational disc portions 142 and 143. In addition, one end of the torsional spring 141 is bent in an opposite direction. The input end of each rotational disc portion 142 is connected with the output end of the corresponding single-directional input bearing 13 and the output end of rotational disc portions 143 is connected with the Accelerating gear 15 (please see Fig. 2A). When the accelerating gear 15 are inactivated, the rotational disc portions 143 would remain still. Therefore, each rotational disc portion 142 may rotate with respect to the corresponding rotational disc portion 143. When the accelerating gear 15 are activated, the torsion stored in the rotational disc portions 143 may be sped up and then output.
As illustrated in Fig. 2, the energy storage apparatus 1 of the present invention is actually a part of a larger energy supplying system. In this embodiment, such system is a wind turbine. An energy generating unit 2 that may receive rotational energy from wind, water, human or other types of sources is connected with an energy input end 16 of the energy storage apparatus 1. A clutch 51 is provided between the energy input end 16 and the energy generating device 2 and a wind speed measuring device 21 may also be provided so as to determine the activation of the clutch 51 according to the magnitude of the rotational speed. In addition, a transmission box 53 and a flywheel 52 are provided between the energy input end 16 and the clutch 51. The flywheel 52 is provided to stabilize the energy output of the energy generating device 2 and the transmission box 53 is provided to reduce the rotational speed of the energy generating device 2 so as to increase the magnitude of the torsion. As illustrated in Fig. 3, an electromagnetic brake 61, a continuous speed varying box 62, a speed control unit 63, a flywheel 64, a clutch 65 and a generator 3 are provided in the left to right order in Fig. 3. The electromagnetic brake 61 is provided to reduce or stop the energy output of the Accelerating gear 15. The continuous speed varying box 62 is provided to maintain the rotational speed of the energy output. The speed control unit 63 is provided to control the rotational speed of the energy output. The flywheel 64 is provided to stabilize the energy output. The clutch 65 is provided to control the passage of the energy output to the generator 3.
The clutch 51, wind speed measuring device 21, transmission box 53, Torsion limiter 12, energy storage set 14, electromagnetic brake 61, continuous speed varying box 62, speed control unit 63, clutch 65 and generator 3 are connected with a computer control unit 4 to control the overall operation.
As illustrated from Figs. 4 to 11, to enhance the energy storing efficiency, each torsional spring 141has an opposite-direction bending design. A central retaining portion 144 is centrally provided in each input end rotational disc portion 142 and 143. An outer retaining groove 146 is provided at an outer position of each rotational disc portion 142 and 143 and an inner retaining groove 145 is provided in each central retaining portion 144. The inner end 147 of each torsional spring 141i$ retained in the inner retaining groove 145 and the outer end 148 of each torsional spring 141 is bent in an opposite direction and retained in the outer retaining groove 146. There are two types of connective methods for the leaf spring units 141. In the first type, the inner end 147 of each torsional spring 141 is first retained in the inner retaining groove 145 and then the outer end 148 is bent in an opposite direction (i.e., opposite to the winding direction of the leaf spring) and is retained the outer retaining groove 146. in the second type, the outer end 148 of each torsional spring 141 is first retained in the outer retaining groove 146 and then the inner end 147 is bent in an opposite direction (i.e., opposite to the winding direction of the leaf spring) and is retained the inner retaining groove 145. Therefore, a plurality of rotational disc portions 142 and 143 may be linked up by such leaf spring units 141 so as to enhance the energy storing efficiency. In addition, a wavy pattern 149 may be provided on the surface of each torsional spring 141 so as to enhance its energy storing efficiency.
As illustrated in Fig. 12, a plurality of middle rotational disc portions 140 are co-axially provided between each pair of end rotational disc portions 142 and 143. Each input end rotational disc portion 142 at the input end is connected with the output end of the one-way input bearings 13 and each output end rotational disc portion 143 at the output end is connected with the Accelerating gear 15. Also a torsional spring 141is provided between each input end rotational disc portion 142 and each middle rotational disc portion 140 as well as between each middle rotational disc portion 140 and each output end rotational disc portion 143. When the Accelerating gear 15 are inactivated, the Accelerating gear 15 may lock up the output end rotational disc portions 143 so as to allow the input end rotational disc portions 142 to rotate and thus store energy. In the mean time, the leaf spring units 141 would cause the middle rotational disc portions 140 to rotate so as to store the energy until no energy can be input. When the speed increasing cog-wheels are activated, the output end rotational disc portions 143 may cause the middle rotational disc portions 140 and the input end rotational disc portions 142 to rotate to speed up the output of energy through the leaf spring units 141.
Fig. 13 illustrates another embodiment. The energy storage set 14may be arranged in parallel and the cog-wheels may distribute the energy to the energy storage set 14; also, energy may be output through the Accelerating gear 15. In addition, each of the energy storage set 14has its own torsion magnitude limiting unit 12 and single-directional input bearing 13.
The energy storage apparatus of the present invention has the following advantages: 1. The energy storage apparatus of the present invention may be used for various types of energy generating unit to store energy through spring torsion. In addition, the energy storage apparatus may release energy when the energy generating unit stops to supply energy and may store energy when the energy generating unit continues to supply energy so as to maintain a continuous energy output. 2. In the energy storage apparatus of the present invention, a steady energy output may be maintained: energy generated by an energy generating unit is first input into the energy storage apparatus of the present invention and then is output in a steady magnitude through the adjustment of proper rotational speed. 3. The energy storage apparatus of the present invention has a high efficiency of energy storage and takes up a limited amount of space. Therefore, the device of the present invention is quite useful. 4. The energy storage apparatus of the present invention may used inside motor vehicles, electric fans, shaver, toy cars and other devices that utilizes rotational energy. The device of the present invention may also be used with a small
